Specification of Letters Patent. .Lpplioation filed September-.29, 1905. Serial No. 380,691- 1 DUMPING AND c eme APPARATUS FOR MINE-CARS- Patented July 31, 1906.

Be it known that I, THOMAS Flat citiinvented certain new and useful ments in Dumping and Cagin Apparatus of which the fo lowing is a specification containing a full, clear, and exact description,reference being had to the accom anylng drawings, forming a part hereof.

Mg invention relates to adumping and caginga paratus for mine-cars.

The Oh Improverequiring ut a single attendant and adapted cage loaded cars at the bottom of the-shaft.

To the above purposes mylinvention' con sists in certain novel features of construction, which .will be hereinafter more clearly set forth, pointed out in my claims, and illustrated 'in the accompanying drawings, in which- Figure 1 is a vertical section showing my improved apparatus in use for dumping a car .at the top of, a mine-shaft. Fig. 21s a longitudinal section taken through the center of the cylinder of my improved apparatus and the pivoted beam that carries said cylinder. Fig. 3 is an enlargedvertical section taken. on the line 3 3 of Fig. 1. Fig. 4 is an enlarged horizontal section taken on the line'4 4 of Fig. 5 is an enlarged horizontal section taken onthe line 5 5 of Fig. 3 and showing the four-way valve I make use of in carrymg outmy invention.

Discharge-cocks 20 are arranged on the under side of the cylinder 12 at each end thereof for the purpose of allowing for the this hook is transversely corrugated, as indidischarge of any water of condensation or exmight accumulate within the cylinder.

Extending outwardly from the right-hand one of the posts 7 is a bracket 21, ontop of which is arranged a four-way valve 22, that is manipulated by a handle .One. side of this four-way valve-is an inletpipe 24,-in which is located a suitable inletva the four-way valve downward y through the bracket 21 is an exhaust-pipe 26. Leading from the sides of the four-way valve are ipes 27, in which are located suitable reguating-valves 28. The ends of these pipes 27 terminate adjacent the right-hand one of the posts" 7, andv to said pipes are fixed in any suitable manner the mner ends of suitable flexible tubes 29. These flexible tubes extend to the ends of the cylinder 12, and their outer ends arefixed in any suitable manner to short pipes 30, one of which enters the side of the cap 14 and the opposite one enterthe .c linder 12 to move the piston 15 backward y and forwardly'therein.

Leading into ve 25., Leading from theolpposite side of I00 ing the side of the cylinder 12, adjacent the Secured to the top of the beam a short distance from the front end thereof is a loop 3 31, to which is attached the lower end of a chain 32. The upper end of this chain is secured to the lower end of a rod 33, that exq tends upwardly through a timber 34, carried by the roof 8 and there being a "shaft, the beam and cylinder are arranged at such a height as that when a car is brought by the cage into a position where it can be moved onto the dumpinglatform 6 the upper edge of the rear wall 0 the car 4 occupies a position between the depending 'aws of the onto a screen or chute.

hook 18, the piston 15 at this time eing at its rearward Hunt of movement. 7

The operator of my improved apparatus is stationed at the right-hand side of the beam and cylinder and adjacent the bracket 21. To bring the apparatus into operative condition, the valve 25 is opened and suitable fluidpressure passes through the inlet-pipe to the four-way valve 22. This valve has been so manipulated as that the fluid-pressure will pass through the tubular connections 27, 29, and 30, that lead to the front end of the cylinder, and thus said pressure is delivered to a point in front of the piston 15. This action maintains the piston 15, iston-rod 16, and inverted U shaped hook 18 at their rear -ward limit of movement, said hook being adapted to engage-the rear wall of the car 4. When the car has been brought to the proper height by the cage and it is desired to dump said car, the operator reverses the position of the four-way valve and allows the fluid pressure to pass from the pipe 24 through the tubular connections 27, 29, and 30, leading to the rear end of the cylinder. Thus the pressure is applied to the front side of the piston, and as a result said piston, piston-rod, and

'hook 18 carried thereby are moved forwardly and the car is pushed ofl from the cage 2 onto the dumping-platform 6, and as said platform tilts the contents of the car are discharged The hook 18 during this operation maintains its position on the upper edge of the rear wall of the car, and the cylinder 12 swings or rocks vertically with the beam 10 upon its pivot to accommodate any change of elevation of the rear end of the car. To accommodate this vertical movement of the cylinder and beam, the flexible pipes 29 are provided between the pipes 27 and 30. After the car has thus been dumped the operator moves the four-wa valve back to its normal position, which a1 ows the fluid-pressure to discharge into theforward end of the cylinder and move the piston, piston-rod, and the hook 18 carried thereby rearwardly, and

'thus return the car 4 onto the cage 2.

Whenever the piston moves within the cylinder 12, the exhaust from said cylinder will discharge through the corres ending tubular connect1ons-30, 29, and 27, t ou h the fourway valve 22, and out through t e exhaustpipe 20. Thus the two sets of tubular connections 27 29, and 30 are alternately'mlet and exhaust pipes.

The regulating-valves 28 can be adjusted and set so as to admit just the proper amount of fluid-pressure re uired for movlnglthe 1ston forwardly and ackwardly in t e cy inder 12.

An apparatus constructed in accordance with the foregoing description is simple, strong, and durable, can be 0 erated with any fluid-pressure and by a sing e o erator, and can be advantageously used for umping cars at the to of the shaft or caging cars at'the bottom 0 a shaft.
